Armstrong Fm: The Superior Radio Broadcasting Technology
Armstrong frequency modulation (FM) is a radio broadcasting technology invented by Edwin Howard Armstrong. The Armstrong Memorial Research Foundation and the Armstrong Institute of Radio Engineering and Science perpetuate his legacy. The Armstrong Broadcasting Company played a crucial role in promoting FM radio. Armstrong’s 1933 demonstration to the FCC showcased the advantages of FM over AM, introducing higher fidelity and noise immunity. FM operates by varying the frequency of the radio wave, while AM varies its amplitude. This distinction gives FM superior sound quality, making it the preferred choice for high-quality audio broadcasting.

Armstrong’s journey into the realm of radio began in earnest when he stumbled upon an article about physicist Nicola Tesla’s pioneering work in wireless transmission. Intrigued, he dove headfirst into the world of electronics, spending countless hours tinkering with circuits and experimenting with various forms of modulation.
In 1933, Armstrong’s tireless efforts bore fruit when he invited the FCC to witness the magic of his groundbreaking invention—FM radio. The demonstration was a resounding success, proving FM’s superiority over the prevailing AM technology. Its ability to deliver crystal-clear, static-free audio captivated the audience, leaving them utterly astonished.
Armstrong’s contributions didn’t end there. His unwavering commitment to advancing the field of radio engineering led him to establish the Armstrong Memorial Research Foundation and the Armstrong Institute of Radio Engineering and Science. These institutions served as beacons of innovation, fostering cutting-edge research and nurturing future generations of engineers.
Through his indomitable spirit and unwavering dedication, Edwin Howard Armstrong etched his name into the annals of history as the father of FM radio. His legacy continues to inspire countless individuals, reminding us that the pursuit of knowledge and the relentless pursuit of innovation can yield extraordinary results.

Together, they’re ensuring that Edwin Howard Armstrong’s vision for the future of radio engineering continues to inspire and innovate for generations to come.
Armstrong Broadcasting Company: The Pioneers of FM Radio
Before we dive into the technical wizardry behind FM radio, let’s meet the company that played a pivotal role in its birth and promotion: Armstrong Broadcasting Company.
Imagine a time when radio was dominated by grainy, static-filled AM broadcasts. Enter Edwin Howard Armstrong, the brilliant inventor who dreamed of a crisper, interference-free listening experience. In 1933, he demonstrated his revolutionary invention to the FCC, and with the support of his company, Armstrong Broadcasting Company, FM radio took flight.
Armstrong Broadcasting Company was more than just a business; it was a platform for Armstrong’s vision. They invested heavily in promoting FM, educating the public about its advantages, and building a network of FM stations across the country. Their unwavering belief in Armstrong’s technology helped pave the way for the widespread adoption of FM radio.
As Armstrong Broadcasting Company grew, it became a beacon for FM enthusiasts and a driving force behind the advancement of radio technology. Their legacy lives on in the vibrant FM radio landscape we enjoy today, where we can tune into crystal-clear broadcasts without a hint of that annoying crackling.
**The Magical Moment that Changed Radio Forever: Armstrong’s Demo of FM Radio to the FCC**
Picture this: It’s 1933, and the airwaves are abuzz with excitement. Why? Because the brilliant inventor Edwin Howard Armstrong is about to unveil his revolutionary invention, Frequency Modulation (FM) radio, to the skeptical eyes of the Federal Communications Commission (FCC).
Armstrong, a true pioneer in the field, had been toiling tirelessly in his lab, driven by an unwavering belief in the superiority of FM over the outdated Amplitude Modulation (AM) system. On that fateful day, he assembled a small group of FCC officials at the Armstrong FM station in Alpine, New Jersey, ready to showcase his groundbreaking creation.
With a flick of a switch, Armstrong broadcast a crystal-clear symphony orchestra performance that left the FCC commissioners stunned. The sound was pure, free from the static and interference that plagued AM radio, and it delivered a fidelity that had never been achieved before. It was a moment of triumph, not just for Armstrong but for the future of radio itself.
The FCC’s initial reluctance to endorse FM melted away before the undeniable superiority of the technology. Armstrong’s demonstration had opened their eyes to the vast potential of FM, and they soon granted him the first licenses to broadcast in the FM band. This marked a pivotal point in the history of radio, paving the way for the birth of high-fidelity broadcasting that we still enjoy today.
So, next time you’re tuning into your favorite FM station, take a moment to raise a glass to Edwin Howard Armstrong, the visionary inventor whose groundbreaking demonstration forever changed the way we listen to the world.
FM Radio: The Invention That Changed Radio Broadcasting
Technical Concepts:
Frequency Modulation (FM)
FM radio, the brainchild of Edwin Howard Armstrong, is a revolutionary invention that’s as cool as a cucumber. Imagine your favorite radio station as a roller coaster. In AM radio, the height of the roller coaster represents the volume, and in FM radio, it’s the width. That means FM radio gives you crystal-clear sound, just like a smooth ride on a well-maintained coaster.
Amplitude Modulation (AM)
AM radio, the grandpa of broadcasting, uses a different trick. Here, the height of the roller coaster isn’t just about volume, it also affects the information being transmitted. While AM radio has its old-school charm, it’s prone to crackling and popping like a bumpy road with potholes.
The Difference Between FM and AM
FM radio (frequency modulation) and AM radio (amplitude modulation) are like two different flavors of ice cream. FM is the smooth and creamy one, with its wide band of frequencies (like a big scoop) that produces rich, high-quality sound. AM, on the other hand, is the classic and nostalgic one, with its narrower band of frequencies (like a smaller scoop) that gives you a more traditional radio experience.
Which One’s Better?
Well, it depends on what you’re looking for. If you want crisp and clear music, FM is your go-to. If you prefer talk radio with a dash of nostalgia, AM might be more your style. But one thing’s for sure: both FM and AM have played a monumental role in shaping the world of radio broadcasting.
